Description

Technical Field

[0001] The utility model relates to the technical field of sheep embryo transplantation, in particular to a uterine horn grasping forceps for sheep embryo transplantation. Background Art

[0002] The uterine horn insemination technique of sheep with laparoscopic endoscope can improve the fertilization rate, increase the number of available embryos, and reduce the stress caused by multiple matings. The technique has low trauma, small area of ​​uterine exposure, short operation time, and reduced possibility of infection, so it is widely used. The specific operation is: open a 2 cm opening at 10-15 cm away from the left breast of the sheep, then open a 2 cm opening at 10-15 cm away from the right breast of the sheep, insert a laparoscope at the left opening to find the uterine horn, and use a uterine clamp at the right opening to pull out the uterine horn to obtain the embryo. The heads of existing uterine clamps are relatively sharp, and the uterine horn is easily damaged, which increases the probability of wound infection. Although some uterine clamps can also avoid damage to the uterine horn, the uterine horn will easily slip during the clamping process. In addition, since the operation is performed with one hand (one hand holds the endoscope and the other hand uses the uterine clamp), if you are not careful, the uterine clamp may be held upside down, which brings inconvenience to the transplantation work and reduces the work efficiency of embryo transplantation. However, there are still certain problems when using the existing sheep embryo transplantation uterine horn grasping clamp:

[0003] For example, a uterine horn clamp for sheep embryo transplantation with application number CN201820463595.8 has a technical solution as follows: it includes a clamp handle and a clamp head, there are two pairs of clamp heads, each pair of clamp heads is composed of an angle rod and an oval clamp, the angle between one pair of clamp heads and the plane where the handle, the limit handle and the clamp rod are located is 20° to 60°, and the angle between the other pair of clamp heads and the plane where the handle, the limit handle and the clamp rod are located is -20° to -60°, the clamping surface of each pair of oval clamp heads is wavy, and the oval clamp heads are annular elliptical; the advantages of the utility model: the wavy oval clamp and the tool The clamping surface with arc chamfer not only increases the clamping surface area but also prevents damage to the uterine horn; the clamping surface of the oval clamp is sandblasted with cast iron sand to increase the clamping friction and prevent the uterine horn from slipping; the bidirectional clamp design allows the operator to not consider the direction of gripping, which is convenient to use and increases the work efficiency of embryo transplantation. However, the existing uterine horn clamps for sheep embryo transplantation have a single functionality, and it is difficult to clean the dead corner of the shaft after use in surgery. At the same time, when the staff use their hands to force during use, certain indentations will be caused on the hand joints, resulting in reduced comfort.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In response to the above problems, an innovative design was carried out based on the original sewage purification device. Utility Model Content

[0015] Preferably, a rotating shaft is installed through the first grasping forceps connecting block and the second grasping forceps connecting block, and a cross block is connected to the top of the rotating shaft.

[0016] By adopting the above technical solution, when the first grasping forceps connecting block and the second grasping forceps connecting block drive the movement of the upper forceps rod and the lower forceps rod through the connection of the rotating shaft, the grasping forceps head realizes the grasping and clamping effect. At the same time, when the first grasping forceps connecting block is rotated until the cross slot hole is aligned with the cross block, the first grasping forceps connecting block and the second grasping forceps connecting block can be separated, which is convenient for dividing the grasping forceps into two parts and facilitating the cleaning of the blind corner of the rotating shaft.

[0017] Preferably, a groove is formed on the upper surface of the limit block on the right side of the upper clamp rod, and a groove is formed on the lower surface of the limit block on the right side of the lower clamp rod, and the upper and lower grooves are connected to each other.

[0018] By adopting the above technical solution, when one end of the uterine grasping forceps is held, the butt joint of the grooves when the limit blocks contact each other makes it convenient for the operator to gently pull the uterine horn without the grasping forceps automatically opening.

[0019] Preferably, a spring is installed inside the gripper handle close to the outer edge, and a silicone pad is connected and installed on the other end of the spring.

[0020] By adopting the above technical solution, when using the grasping forceps, the fingers pass through the inside of the grasping forceps handle, and the silicone pad drives the spring to expand and contract according to the width of the fingers. The silicone pad can provide a certain degree of protection for the fingers, and the spacing between the grasping forceps handles can adapt to the space according to the width of the staff's fingers, thereby improving stability and comfort during use.
